I've replaced the .47uF Orange drops with AmpOhm tin foil and oil capacitors available from the Tube Store. I've also replace the .1uF Xicons with Auricaps. After many hours of break-in, I can strongly approve of the AmpOhm units - it has an extremely musical, almost laid back sound that makes you want to spin record after record. It is a good balance to strike with the more lean and forward sound of the 6DJ8 family of tubes.
Regarding tube rolling - I've also tried a pair of Voskhod 80s production 6N23Ps. Though not quite the same quality as the NOS Amperex/Mullard/Telefunken tubes, it has a fast sound that mates well with the AmpOhm oil capacitors.
For a budget tube phono stage, the Bottlehead Seduction is a musical revelation. Though it doesn't compete with my Threshold FET-10/PC in terms of overall detail and bandwidth, the Seduction is certainly no slouch either. Though it lacks the very ultimate in inner detail it is natural, musical and would be a great upgrade over most vintage tube phono units. Now if only it had a White Cathode Follower low impedance output, a regulated tube power supply and... oh, curses I just can't leave anything alone!
